论连续并购与间隔并购样本的差异

在已有对并购的研究中,学者们没有细分连续并购样本和间隔并购样本。他们大多数采取两种方式:一种是把连续并购剔除在外,另一种是把连续并购和间隔并购放在一起,致使我们的并购研究无法突破。本研究选取四大类别熵,即:支持型熵、压力型熵、还原型熵、氧化型熵作为变量,利用参数和非参数检验进行样本的差异检验。最后发现:连续并购和间隔并购有实质性的区别。这给我们今后做并购研究的样本选取提供了有利的支持。

To Demonstrate on Difference of the Samples Between Continuous and Interval Mergers

The scholars have never subdivided continuous merger and interval merger sample .Most of them adopt two kinds of way:One gets rid of continuous merger samples,the other puts continuous merger and interval merger samples together.Both of kinds cause our merger research not to get more success.This article has selected four greatest categories entropy: oxidize entropy,revivification entropy,supported entropy and pressure entropy,as to variables.We make use of parameter and non-parameter examination to demonstrate the difference.In the end,we find that: Continuous merger and partition merger samples have materiality differentiation.This tells us that we must distinguish the samples of continuous and interval mergers and acquisitions.
